# Introduction

> The AI-powered Web3 IDE — write, compile, deploy, and interact with smart contracts from one place

## What is Cheetah AI?

Cheetah AI is a Web3 IDE with AI built in. It's a code editor where you can write Solidity contracts or Solana programs, compile them, deploy them to any chain, and interact with them — all through a chat interface. No terminal commands, no deployment scripts, no browser extensions.

It comes with:

* A built-in crypto wallet (EVM + Solana)
* Foundry compiler and Anvil local node (bundled, no install needed)
* Anchor/Solana toolchain support
* Support for 16+ chains (Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche, BNB, Solana)
* Security auditing (Aderyn)
* AI that understands your entire codebase

  Step-by-step tutorial: install, set up wallet, deploy a smart contract.

## How It Works

You talk to the AI in the chat panel. The AI does the work.

```
"Create an ERC-20 token, compile it, and deploy to local"
```

The AI writes the contract, starts a local blockchain, compiles with Foundry, deploys, and gives you the contract address. You interact with it by saying things like "mint 1000 tokens" or "check my balance."

No `forge build`. No `anvil`. No deployment scripts. No MetaMask popups.

## Key Features

<Columns cols={2}>
  <Card title="Built-in Wallet" href="/docs/web3/wallet">
    Create or import a wallet. Switch between 16+ chains. Send tokens, sign messages, check balances. Works for both EVM and Solana. No browser extensions.
  </Card>

  <Card title="Smart Contract Development" href="/docs/web3/smart-contracts">
    Write Solidity, compile with Foundry, test with forge-std, deploy to local/testnet/mainnet. OpenZeppelin imports resolve automatically.
  </Card>

  <Card title="Solana Programs" href="/docs/web3/solana">
    Build with Anchor framework. Compile Rust programs, deploy to local validator or devnet. SPL token support included.
  </Card>

  <Card title="Local Blockchain" href="/docs/web3/overview">
    Spin up Anvil (EVM) or solana-test-validator with one command. Free gas, instant blocks, unlimited test tokens. Reset anytime.
  </Card>

  <Card title="AI Agent" href="/docs/features/modes">
    The AI reads files, writes code, runs commands, and iterates on solutions. It handles multi-step tasks end-to-end while keeping you in the loop.
  </Card>

  <Card title="Security Auditing" href="/docs/web3/smart-contracts">
    Run Aderyn static analysis on your contracts. Detects reentrancy, access control issues, gas optimizations, and 90+ vulnerability patterns.
